동아오츠카(주)는 청량음료를 제조하는 식음료 제조회사이다. 당초 동아제약 식품사업부에 속해있었으나 1979년 분리되어 식품회사로서 면모를 갖추고 안양에 제1공장을 설립했다. 특히 지난 1980년 청주에 제2공장을 준공한 것에 이어 1996년 경남 함안에 제3공장 칠서공장을 가동하면서 우리나라 청량음료업계에 새로운 이정표를 세웠다. 동아오츠카(주) 하면 제일 먼저 알카리성 이온음료 포카리스웨트가 떠오른다. 그리스 산토리니의 파란 하늘과 바다, 하얀 집이 어우러져 큰 화제가 됐던 포카리스웨트 광고는 국민들의 뇌리 속에 깨끗하고 맑은 회사 이미지를 각인시키기도 했다. 그 밖에도 검은콩을 우려낸 블랙빈테라티, 녹차음료 그린타임, 과즙음료 데미소다, 콩과 과일을 구워낸 소이조이, 허니레몬 등의 기능성 음료와 한국인의 청량음료라고 할 수 있는 오란씨 등이 대표적인 제품이다. 동아오츠카(주)는 소비자의 요구에 맞게 맛과 기능을 조화하여 21세기 건강 지향 기능성 음료를 만들겠다는 신념으로 세계 음료시장을 개척해나가고 있다. 때문에 제품의 품질을 좌우하는 '안전'이 기업경영의 초석이 되고 있다. 1998년 동아오츠카(주) 칠서공장 무재해 목표 개시 후 14년간 '무재해 12배수' 달성이 가능했던 것도 바로 이 같은 철저한 안전 관리가 원동력이 됐기 때문이다. 안전경영을 바탕으로 우리나라 음료 소비 패턴을 주도해가고 있는 동아오츠카(주) 칠서공장을 찾아가봤다.

Currently, there are a total of 68 emergency rooms based on Seoul, South Korea, and there is a portal site that allows you to inquire the location of the emergency room, but it is difficult to use in an actual emergency situation because it consists of selecting a gu and a self-governing dong. In addition, it may be more efficient to go to the emergency room directly because you may miss the golden time necessary for survival in a situation where you call 119 and wait for the rescue team. Therefore, in this paper, we propose a service that can quickly search the location of the emergency room based on a specific location through various functions supported by MongoDB. After downloading emergency room location data based on Seoul Metropolitan City, storing it in MongoDB, processing the data through various processing techniques, and applying a spatial index, you can query the emergency room based on distance from a specific location in real time.

본 연구에서는 물순환 왜곡이 심화되고 있는 도시 하천유역을 대상으로 택지개발과 같은 도시화로 인한 영향을 검토하고, 개발로 인한 영향을 최소화할 수 있도록 적정 우수저류침투시설을 계획..설계하는 것을 목적으로 하였다. 도시화 전후의 물순환의 변동특성은 WEP(Water and Energy Transfer Processes) 모형을 활용하였으며, 택지 개발 지구내 우수저류침투시설은 독일 베를린공대와 한국건설기술연구원이 공동 개발한 '공동주택 빗물관리 최적화 모형(가제)'을 활용하여 모의하였다. 대상 하천유역은 의왕시 청계동 및 포일동 일원에 도입예정인 의왕청계지구 택지개발지구를 포함한 안양천 상류의 대한교 상류유역이다. 단지 개발 전후 토지이용특성이 대부분 밭에서 중고층 주택지역으로 변경됨에 따라 불투수면적 비율이 10.5%에서 15.7%로 증가하였으며, 이로 인해 침투량, 증발산량, 지하수 유출량의 감소, 지표면 유출 및 하천으로의 유출량이 크게 증가하는 것으로 나타났다. 도시화로 인한 물순환 체계의 건전화를 위해서 우수저류침투시설의 도입이 필요할 것으로 판단된다.

This paper proposes the new narrow erase method to erase wall charges formed in an AC plasma display panel (PDP) cell. In the proposed method, pulse timing of switch at the sustain period is adjusted for inducing, a weak discharge. Then, after the narrow erase, the voltage of the X electrode is set to differ from that of the Y electrode. For the proposed method, the measured maximum address voltage margin was 38.3V at Y_Rest voltage of 100V and sustain voltage of 180${\sim}$185V. However, for the conventional method, in which the X and Y electrodes are set to be of equal voltage after the narrow erase, the measured maximum address voltage margin was 31.3V at Y_Rest voltage of 150V and sustain voltage of 180V. This result shows that the measured maximum voltage margin for the proposed method is about 7V(22%) higher than that for the conventional method.

This study quantitatively evaluates the economic value of an intelligent crime-zero testbed by using the contingent valuation method (CVM), which is the most effective for non-market valuations in fields like crime prevention. To minimize hypothetical convenience and increase respondents' awareness regarding the actual situation, an analysis was conducted for Indukwon District, Anyang City, Gyeonggi-do, by using the intelligent crime prevention technologies and solutions being developed by the KICT Research Center. This analysis was aimed at providing a systematic basis for determining the feasibility of crime prevention-related public projects. As a result, the WTP of Anyang citizens in the intelligent crime prevention demonstration district was estimated to be 7,160 won. The analysis shows that the area of Gwanyang 2, where the test bed belongs, has a high economic value of KRW 660 million per year, and KRW 51.4 billion per year when expanded to Anyang City. This study is significant in that it provides the first domestic evaluation of the crime-zero testbed. In addition, it has academic and practical value for a future-oriented service model by using intelligent crime prevention technologies and solutions that can be applied in real life and to the crime-zero testbed.

In this study, spatial patterns of the urban flood vulnerability index in Seoul are examined by considering climate exposure, sensitivity, and adaptability associated with floodings for recent 5 year (2006~2010) period by the smallest administrative unit called Dong. According to the results of correlation analyses based on the IPCC(Intergovernmental Panel on Climate Change)'s vulnerability model, among many variables associated with urban flooding, rainwater tank capacity, 1-day maximum precipitation and flood pumping station capacity have statistically-significant, and relatively-high correlations with the number of flood damage in Seoul. The flood vulnerability map demonstrates that the extensive areas along Anyang and Joongnang streams show relatively high flood vulnerability in Seoul due to high sensitivity. Especially in case of Joongnang stream areas, climatic factors also contribute to the increase of flood vulnerability. At local scales, several Dong areas in Gangdong-gu and Songpa-gu also show high flood vulnerability due to low adaptability, while those in Gangnam-gu do due to high sensibility and climate factor such as extreme rainfall events. These results derived from the flood vulnerability map by Dong unit can be utilized as primary data in establishing the adaptation, management and proactive policies for flooding prevention within the urban areas in more detail.

Recently, a self-camera that generates and distributes a large amount of moving images has been rapidly increasing due to the appearance of SNS such as Facebook, Instagram, and Tweet using mobile. In particular, the amount of SNS connections using mobile phones is significantly increasing in terms of usage, number of connections, and usage time. However, the use of a self-recording system using a smartphone by itself is extremely limited not only in terms of usage but also in frequency of use. In addition, the conventional unattended recording system is a very expensive system that automatically records and tracks an object to be photographed using an infrared signal. Therefore, this paper developed a low cost unmanned recording system using mobile phone. The system consists of a commercial mobile camera, a servomotor for moving the camera from side to side, a microcontroller for controlling the motor, and a commercial wireless Bluetooth earset for video audio input. And it is an unmanned automation system using mobile, and anyone can record image by self image tracking.

Low-cost, ultra-high-speed cameras, made possible by the development of image sensors and small displays, can be very useful in image processing and pattern recognition. This paper introduces an algorithm that corrects irregular lighting from a high-speed image that is continuously input with a slight time interval, and which then obtains an exposed skin color region that is the area of interest in a person from the corrected image. In this study, the non-uniform lighting effect from a received high-speed image is first corrected using a frame blending technique. Then, the region of interest is robustly obtained from the input high-speed color image by applying an elliptical skin color distribution model generated from iterative learning in advance. Experimental results show that the approach presented in this paper corrects illumination in various types of color images, and then accurately acquires the region of interest. The algorithm proposed in this study is expected to be useful in various types of practical applications related to image recognition, such as face recognition and tracking, lighting correction, and video indexing and retrieval.

An unattended recording system based on smartphone based image image tracking is rapidly developing. Among the existing products, a system that automatically tracks and rotates the object to be photographed using an infrared signal is very expensive for general users. Therefore, this paper proposes a mobile unattended recording system that enables automatic recording by anyone who uses a smartphone. The system consists of a commercial mobile camera, a servomotor that moves the camera from side to side, a microcontroller to control the motor, and a commercial wireless Bluetooth Earset for video audio input. In this paper, we designed a system that enables unattended recording through image tracking using smartphone.
